Vilros 40 Pin Hammer-in Pin Header for Raspberry Pi Zero with Install Rig---Easy Pinheader Installation Solution for a Raspberry Pi Zero----No Soldering Required

This rig and pin header was very easy to use. Some even and gentle taps with a hammer, check to see if the header is flush with the board, and repeat if necessary. Took me 3 times of even and gentle tapping on the strike bar to get the headers flush with the board. Probably 2 minutes worth of tapping saving me who knows how long of soldering/resoldering since I'm not good at it.

Not much to say about this one, works as intended. No frills, just fairly decent quality (probably better than needed for my single use).The included header was actually better quality than the ones I ordered separately, nice touch!

To get a perfect installation, you have to shim under this. The pins will hit the shims. Shortened popsicle sticks or balsa wood work nicely. I was going to dock a star, but Pi projects always require a bit of creativity.

Overall, this device works as advertised. It's easy to align the Pi Zero and stack the top components (hammer bar). However, even though this device clearly is designed to be used with a hammer, I would suggest using c-clamps instead. The jarring force of a hammer could quickly damage any misaligned pins or the Pi Zero.If you are using numerous Pi Zeros, then this device could start to pay for itself in time saved. But I think for most users it might be just one or two Pi Zeros and for that I think this is overkill at this price point.

The compatible header that was supposed to come with the installation kit was missing.
